Anthem D2/D2v/AVM50/AVM50v/ARC1 tweaking guide - Page 1043

Hi,

although not related to the specific issue you are working with Bob on,
here's a good interactive frequency chart which I use to better understand why some speakers sound totally different than others, with or without equalisation.

Hope this helps. Cheers.

Mine is not perfect, and it's not as good as jayray; but, it's not bad. Anyway, take a look and decide if it's something you would like to shoot for.

Here is my chart. Ninja12 has also a very good chart. Note the Red measured curve. It is fairly flat from 100 to 20 Hz. Now the target is set by how good the measurement is. So now the calculated is very close to excellent.

Covered Here

Do you know if ARC will apply filters below 20 Hz if it's set to Auto?

Thanks guys. Not sure if I will get time today to do this but will see later on.

As far as I know in v3.0 they extended the lowest filtering down to 'below 20Hz'. It seems the only mode this could work in is 'Auto' since we've found the 'lowest fq filter' possible in the other modes is 20Hz.

I haven't actually tested to see how low ARC filters in Auto yet.

Cheers

Cool. Thanks for your responses.

Cool charts ...Thanks TKO1!

Thanks Bob for your patience and understanding

Hi, I am searching around for an answer.
thought i'd post here also.

Woke up at 2:30am , heard noise in the living room, "static"
so I went to check it out, it was the AVM50, I have not updated this thing in 6months or so.
Not sure whats on it currently can post later if needed...lol

but back on track, the FM tuner was on so I shut it off... about 2 min later its back on, so I change it to TV shut it down, about 2-3 min later again back on, shut it down, 2-3 min back on, happened 4-6 times I said eff this I'm tired unplugged it and went to bed.
well ok i stopped on here first and searched the web.

found the posts by user usxplong, so I will try that, but strange now two of us having this issue??
usxplong, did you ever find out the resolve to it?

Same problem here with my new AVM-50v just arrived off the production line. Was this ever solved or explained?

How do I get them to negotiate for LPCM instead of Bitstream? It plays as 5.1 but when I pause the movie the Anthem shows 7.1!

Hey bob, I just ordered in the AIX blu Ray Audio Calibration Disc HD Music Sampler specifically to help check the phase of the sub with my main speakers. I do not see a test chapter for this. They have a phase chapter but it does not inlcude a comparison with the sub. What are you using?

when i play a 96khz source (in this case AIX cal disk) from my PS3 (PS3 set to output up to 96khz) via PCM HDMI to the D2 (1.45F) the D2 does not recognize the input as 96Khz when i check status via the remote. The PS3 shows that it is outputting 96. Interestingly, when I bring up the video status screen on the D2 it shows an input of 96Khz in that menu. However, when i check that status of the input via multiple hits of the select button on the D2 remote it brings up 48Khz. Is this just a bug? Which to believe?

Hi Everyone

Is it possible to completely bypass video processing in AVM50v if I am using external video processor?

Thanks

SELL your Video Processor

AM50v Video Processor is just as good.

I talked to Anthem. They sent me a new face plate. It is very easy to install. Only a few screws from inside and the whole face assembly comes off. But I took it to a dealer and installed it in a few mins and everything works perfect so far.

my whole screen is PINK... but my connections are HDMI.
so after the whole, turning on by itse;f unit. I tried reinstalling 1.33 on my AVM50 and redoing the ARC new version. now my TV is one full color... PINK.

thanks for that info, I did the reload as BOB suggested to you, but now I'm having another issue.. PINK screen of death...lol

I doubt that. In any case I cant take video processor out of equation as it is SIm2 LUmis HOST . You need HOST to transmit optical video signal to projector. So I would rather not have 2 processors altering the signal.

can someone please look at my new charts i did some changes after i've been reading on here , let me know what i need to do to get some better results. thank u

You might want to try a flash erase and then do another firmware upload.

Have you altered the room gains? If not, your speakers look good. The sub has a dip from 50 - 80 Hz of around 5 dB, that could be eliminated by moving your sub. If the red measurement line moves up higher, this would result in a better target and ultimately a better green correction. curve. See my post #31263, on this page, showing my sub chart. Notice the red curve is fairly flat from 100 -20 Hz. so the correction is very smooth. Good measurement results in great correction.
John

i did try that and it worked. thx Jayray, how have you been? talked to Neil lately?

I'm going to upgrade to the v , AVM50v just waiting on a price , plus two more speakers and the MCA2. lol just a few bucks.

I'm good as is Neil. Haven't been in since I picked up my MRX. The AVM50v is a great unit, you'll love it.
John

No You can't bypass the video.

no, that is what arc came up with for the gain,is there anything i can do in arc to try to help get the dip out of the sub, i've been trying to move the sub around,but with no luck yet i need to get a longer cable.otherwise you think everything looks good? the only thing that gets it up to the red line is when i lower the frequency on the sub in arc to below 60 but these were the measurments that arc came up with, and i must say it still sounds really good....

Don't change the cutoff freq. in ARC. Try again with the longer cable. And make sure the crossover freq. is turned up as far as it goes ie. to bypass or 180 Hz and then measure. Your other speakers look very good. While it sounds good to you now, if you can fix the dip in the sub it will give you a little more impact. My sub cutoff is 120.

Use System Calibration > Subwoofer Crossover Test

This will sweep a test tone back and forth across the crossover frequencies.

Use it like this:

IMPORTANT NOTE: Be sure your speaker distance settings are correct before you adjust Phase for the sub, as phase is also a function of relative distance.

1) Do an ARC setup. This will establish the crossover frequencies, volume balance the speakers, and eliminate any response defects from the speakers that will interfere with your ability to hear phase related changes.

2) Run the Subwoofer Crossover Test and listen to see if you have uniform volume all across the range. Since ARC has already balanced things and removed defects, any dip you hear will be due to phase cancellation between the Sub and LF. Since different setups will have different crossover frequencies, that dip may occur higher or lower in the sweep range in your setup.

3) Adjust sub phase to eliminate any such dip and get as close as you can get to uniform volume across the frequency range of this test.

Note that phase settings near the correct setting will sound very similar. Add to that some typical listener bias and you'll see that you may undershoot or overshoot the correct phase setting. To counter that, find phase two ways: First sneaking up from below and second dropping down from above. If you come up with two different answers then split the difference between them and that will be your correct phase setting.

4) If you have only one sub, you are now done. Your prior ARC solution still applies and will now just work better. If you have more than one sub then you must re-Measure for ARC after changing phase for any sub as phase setting changes will change what ARC hears from the combo of subs playing together.
